More than 2,000 miles away from the glitz and glamour of the Oscars, a determined group of Hollywood heavyweights used the collective weight of their influence to raise more than $140,000 for residents of Flint, Michigan.

Folks are standing up for Flint! Since last night's #JusticeForFlint show, 3635 activists have raised their voices w/ $145k toward recovery!

The stars, brought together by directors Ava DuVernay and Ryan Coogler, were among a group of African-American artists who turned out in Flint to bring attention, and desperately needed resources, to residents who'd been poisoned by their city's lead crisis for more than a year. They held a massive, livestreamed concert called Justice for Flint.

10. Dr. Mona Hanna-Attisha got a hero's welcome.

It was a chance dinner in August that led pediatrician Mona Hanna-Attisha to begin testing lead levels in the blood of kids in Flint. Since then, she's been credited with helping uncover the heartbreaking consequences of the devastating crisis, namely the fact that lead poisoning levels for the city's children had doubled since officials decided to switch its water source.

She took the stage on Sunday night to tell the community — and, thanks to the livestream, the world — what's at stake. "This is a human issue," she told the crowd. "This is not a political issue."
